RAIL ANCHOR.

Applieation filed March 16, 1925, Serial No. 15,775. Renewed June 1, 1926.

My invention relates to rail anchors adapt ed to grip the base of a railroad-rail and abut against a tie to resist the longitudinal movements of the rail, and its primary object is to provide a new and improved device of this character which has means at its ends to engage the opposite sidesof the rail-base and also affords an engagement at one end to interlock with the corresponding edge of the rail-base. I

In the accompanying drawings, Fig. 1 is a top plan view showing a rail anchor constructed in accordance with my invention and assembled in place on a rail-base and at one side of a rail-tie; Fig. 2 is a cross-sectional view on the line 2-2 in Fig. 1 looking in the direction of the arrows; Fig. 3 is an end'view of the device in place on a rail with a portion of atie in section; and Fig. d is a detail sectional view on the line 52-4 in Fig. 2.

In the drawings the reference letter A designates the head of a rail, B 1ts base and C its web, and D is one of the crossties on which the rail is supported, being spiked thereto as at d.

The rail anchor consists of a rectangular metallic plate having a flat base or body 1 which is provided on its top surface near one end with an overhanging lip 2 and near the other end with an upwardly extending flange 3 which provides a rail-abutting shoulder 4 at its lower inner portion and is preferably rounded ofi or beveled outwardly as at 5 on its inner face. The plate is provided with a longitudinal central slit (3 which extends from near the lip 2 through the opposite end of the plate and through the flange 3, thereby dividing that end of the plate into two sections or wings indicated at 7 and 8, and dividing the flange into two sections, so that when a suitable wedge is driven to place between the sections of the flange they will be spread apart to engage and interlock with the edge of the rail-base. The sections of the flange are provided with opposite apertures 9 open on the side of the slit 6 and forming a seat for a wedge 10. The wedge-seat is preferably arranged or disposed at an obtuse angle to the inclined upper face of the rail-base, so that as the wedge'is driven to place its inner end rides up the base and curls or bends upwardly, as shown for example in Fig. 2, whereby it wedges on the base and.

its sides bind against the upper portions of the flange sections on each side of the slit to prevent its accidental displacement or withdrawal. The inner end of the wedge bears upon the rail-base with .a drive-fit, and as the contour of the underside of the lip'2 is preferably made to afford a drivefit with the rail-base, the plate firmly grips the rail at both ends.

The dimensions of the parts of the plate are such that when it is assembled upon a rail-base one edge of the latter fits under the lip 2 and the other edge abuts against the shoulder 4 as shown in Fig. 2; in assembling the plate on the rail the lip 2 is hooked onto one edge of the'rail-base and the opposite end of the plate is then moved up until the corresponding edge of the base seats against the shoulder 4, the rounded or beveled face of the flange permitting the railbase to' pass to place and crowding its opposite edge under the lip. hen the plate is thus assembled upon a rail-base and the wedge is driven into its seat the lateral sections of the split flange are spread apart so that the outer edges of their shoulders move mort or less at an angle to the rail and bind on or bite into the edge of the rail-base as indicated in Fig. 4, to interlock the plate and rail so that there is no lost motion or play between them. At the same time the pressure of the spreading flange sections on the rail wedges the opposite side of its base under the lip 2. By this construction the plate grips both sides of the rail and is interlocked with it. In practice the plates are assembled upon the rails in position to abut against the ties, so that the longitudinal movements of the rail in one direction are transmitted to the ties, which resist the same as they are embedded in the track ballast. In practice I prefer to provide the plate with a depending marginal wing 11 on the side which abuts against the tie in order that the vertical motion of the rail due to its wave-like movement under traflic will not raise the plate above the plane of the upper surface of the tie. The Wing 11 may be extended down throughout its length or at one end as shown in Fig. '2 if desired, so that in case'the upper edge ofthe tie is rounded off the wing will not rise above the top of tie. I also prefer to provide the plate with a depending marginal strengthening rib 12 on its other side.

I claim:

1. A. rail anchor-plate comprising a base having an upper flange at one end and an overhanging lip at its other end, the base being provided With a longitudinal slit extending through said-flange to term lateral sections thereof, and a Wedge to spread the flange-sections.

2. A rail anchor-plate coinprisinga base having an upper'flange at one end and an overhanging lip at its opposite end, said anchor-plate having a longitudinal slit extending, through said. flange to form lateral sections thereof, a wedge-seat in the flangesections,'and a Wedge in said. seat to spread said sections and bear upon an associated rail-base.

3. it rail-anchor plate havinga depending marginal Wing, upper flange at one end of said anchor-plate andv an overhanging lip at its other end, said anchor-plate having a longitudinal slit extending through said flange to forum lateral sections thereof, a wedge-seat in said flange-sections at an angle to. the upper surface of an associated rail-base, and a Wedge in said seat spreadingi said flange-sections and bearing upon the rail-base.

A railanchor-plate comprising a base having rail-eng-agii'ig members near its ends and having a longitudinal slit extending from near one end through the other end and dividing the associated rail-engaging member into seet-ions, and a Wedge to spread said sections.

A rail anchor-plate comprising a base having rail-engaging ineinbers near its ends and having a longitudinal slit extending through one end: and dividing the asseciated rail-engaging. member into sections, a Wedgeseat in said. sections, and a Wedge adapted to be driven into said seat in \v-edgin engagement with a. rail-base on the plate and in locking engagement with said seat-sections.

6. A rail anchor-plate comprising a base having railengaging members near its ends and having a. longitudinal slit extending from near one end through the other end and dividing the associated rail-engaging member into Sections, a Wedge-seat in said sections at an obtuse a igie to the upper surface of an associated rail-base, and a Wedge in said seat to spread said sections and bear on the rail base.

In testimony whereof I hereto a'lfix my signature.
